Becoming a manager changes your job overnight. You are no longer judged on your own work, but on how well your team does. Here are new manager tips for the first day, the first week and the first 90 days.
Direct answer
In your first 90 days as a new manager: listen and learn before you change anything, meet each person one on one, set clear expectations and goals, start regular one-on-ones, deliver one or two small visible wins, and ask for feedback on how you are doing. Avoid the traps of doing the work yourself and changing everything at once.
Before you start
- Ask your own manager what success looks like in the first 90 days.
- Find out how your team's work is judged.
- Write down what you want to learn about each person.
Your first day
- Introduce yourself briefly. Who you are, what you value and that you want to listen.
- Do not announce changes. You do not know enough yet.
- Ask questions. "What is working well? What is frustrating?"
- Remember names and details. It signals that you care.
Your first week
- Meet each person one on one, even for 20 minutes. Ask about their work, what they want to learn and how they like feedback.
- Learn the main processes and where they slow people down.
- Meet your key stakeholders: people who rely on your team.
- Write down what you hear, patterns matter more than single comments.
Your first month
- Share a simple picture of the team's goals.
- Start regular one-on-ones, using the person's agenda first.
- Check roles are clear: who owns what.
- Fix one or two small, visible irritations, such as a broken process or an unclear form. Quick wins earn trust.
Months two and three
- Set clear goals for the team and for each person.
- Practise delegation: hand over outcomes, not only tasks.
- Give specific feedback early and often. See how to be a good leader.
- Have the hard conversation you have been avoiding, privately and kindly.
- Ask your team: "What should I start, stop and continue?"
Common mistakes
| Mistake | What to do instead |
|---|---|
| Doing the work yourself | Delegate outcomes and coach |
| Changing too much too fast | Learn first, change one thing at a time |
| Avoiding hard conversations | Address issues early and privately |
| Being everyone's friend | Be friendly and fair, clear on standards |
| Never asking for feedback | Ask once a month |
If you manage former peers
Be open about the change, keep confidences, treat everyone the same and talk to each person early. Expect some awkwardness at first.
Tools to use
- One-on-one notes (a simple shared document works)
- A weekly goal list for the team
- A "decisions made" log so people know what was decided and why
